Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Configuration

AFCTL_CONFIG

The Application Frontend Command Line Interface creates and uses configuration file, which may be found in $HOME/.afctl/config.yaml. It includes multiple configuration profiles that allow to easily switch between various Application Frontend API servers and users. After successfull login, the configuration file also includes JWT (JSON Web Token) that is used to authenticate the calls of command line interface to Application Frontend service API server. To use configuration file different from default, set AFCTL_CONFIG environment variable to file path of desired configuration file.

AFCTL_COLORS

The Application Frontend Command Line Interface recognizes whether it is printing messages to terminal or not (e.g., output may be piped to file). By default, the messages printed to terminal are colorized using special character sequences (e.g., \u001b[0;90m). If your terminal does not support colors or you would like to explicitly switch off colorization, you can set AFCTL_COLORS to one of the falsy values (false|off|no|0).

AFCTL_LOG_LEVEL

The Application Frontend Command Line Interface supports multiple log levels:

  • 0 - no logs
  • 1 - errors only
  • 2 - errors and warnings
  • 3 - errors, warnings and information messages
  • 5 - verbose logs with all messages (useful for troubleshooting and development). The log level may be controlled by setting AFCTL_LOG_LEVEL environment variable. The default value is 3. If --verbose global flag is used, the log level is 5 (overrides the value set by environment variable).

AFCTL_ACTIVATE

By default, the Application Frontend service activates newly deployed application versions. The behavior may be changed by:

  • push command --activate or --no-activate argument (for single command execution)
  • push command --config config.json configuration, where config.json '{"activateVersion":false}' (for command execututions using this configuration file)
  • AFCTL_ACTIVATE environment variable (for every command executions)

AFCTL_POLLING_MAX_ATTEMPTS

During deployment with push command, there is a polling of deployment status. By default, there will be 120 attempts to fetch the deployment status. After the threshold is reached, the push command will fail (while deployment itself may still be in progress). To support long running deployments for large applications (>100Mb), it is possible to change the maximum number of polling attempts with AFCTL_POLLING_MAX_ATTEMPTS environment variable. The value must be positive integer.

AFCTL_POLLING_DELAY

During deployment with push command, there is a polling of deployment status. By default, the delay between polling requests is 2 seconds (2000ms). To set different delay, it is possible to set AFCTL_POLLING_DELAY environment variable. The value must be positive integer (in milliseconds).

If multiple options are used, the command argument has a higher priority than configuration file, and configuration file has higher priority than environment variable.

AFCTL_XSAPP_TEMPLATE

By default, the init command either uses the xs-app.json in the current working directory (if it exists) as template for the target xs-app.json or creates a brand new xs-app.json. To specify different path to the file that should serve as template for the target xs-app.json, the AFCTL_XSAPP_TEMPLATE environment variable may be set. The template file content should be valid JSON. The route to serve static content from Application Fronted service will be added to the template, if it's not already exist. All routes pointing to html5-apps-repo-rt service will be changed to point to app-front service instead.

AFCTL_MANIFEST_TEMPLATE

By default, the init command either uses the manifest.json in the current working directory (if it exists) as template for the target manifest.json or creates a brand new manifest.json. To specify different path to file that should serve as template for the target manifest.json, the AFCTL_MANIFEST_TEMPLATE environment variable may be set. The template file content should be valid JSON. The application name an version will be added to the template or will replace the relevant values, if they are already present in template.

AFCTL_SAVE_ZIP

By default, the push command creates ZIP of ZIPs in memory and deletes it, once command is finished. To keep generated ZIP and save it to file system, the AFCTL_SAVE_ZIP environment variable may be set to any non-empy and non-falsy value. In this case apps.zip will be saved to current working directory.

AFCTL_TRACE

The path to the file, which will contain the traces of executed command.

Troubleshooting

If you experience unexpected behavior, the execution of command never ends, you see error messages or stack traces in the output - you can run any command with global --verbose or just -v at the end. This will print trace logs with detailed information about each step in the command execution.
